How to Protect USB Disks with Panda USB Vaccine

Some malware infect your USB keys by creating an autorun.inf file on it. So when you insert this USB pen disk in another clean computer, that computer is also infected. You can immunize the USB disks and your computer by using a freeware tool from Panda Security Labs – called Panda USB Vaccine. The Panda USB Vaccine supports Windows XP, Vista, 7 and 8.

You can download Panda USB Vaccine from Panda Security Lab’s web site. Double click on the setup file to install the Panda USB Vaccine. During the setup you are presented with a configuration screen. Do no choose the NTFS Support as it is still in beta experimental state. If you choose the Automatically vaccinate any new inserted USB key option, then all the non-vaccinated USB disks you insert will be auto-vaccinated (read about this later in the article).
